INSPECTION AND
MAINTENANCE
4.1 - GENERAL RULES FOR THE SERVIC-
ING GENERATORS
The yield and duration of a generator depend
not only on a proper installation but also on
good operation and maintenance.
Routine maintenance is essential in the in-
terest of the safety, efficiency and durability
of the appliance.
All maintenance must be carried out by qual-
ified personnel.
Failure to perform Inspections and Main-
tenance can entail material and personal
damage.
All cleaning and maintenance operations
must be preceded by closing the fuel supply,
after having disconnected electricity.
To ensure correct functioning and maximum
efficiency of the generator, you should prop-
erly clean the combustion chamber, smoke
pipes and smoke chamber: on average every
3 months for combustion with dense naph-
tha, every 6 months if using diesel oil and
once a year with the use of gaseous fuels.
Observe the following guidelines:
- Before cleaning the flue gas side, we recommend analysing
the combustion to ascertain the operating conditions, to be
compared with those performed after cleaning.
- Periodically check the proper operation and integrity of the
seals of the fumes evacuation pipe; if you need to perform
work or maintenance of structures located near the fume
ducts and any accessories, stop the generator.
- When work has been completed and before restarting the
generator, you must check with the intervention of a special-
ised technician the efficiency of the smoke ducts, chimney
and in general all the components of the fume extraction
circuit.
- At every start, after a period of inactivity, it is necessary to
repeat the previously described start-up procedures.
- Immediately remove any unburned gas leaks by replacing
the worn seal gaskets.
- It is forbidden because dangerous, even
partially obstruct the air vents for the cor-
rect ventilation of the boiler room.
- It is absolutely forbidden to touch the hot
parts of the generator which are heated
and therefore burn. The same caution
should also be used for at least the next
hour to turn off of the burner.
NOTE
It will be the maintainer's responsibility to
keep the control unit handbook updated, re-
cording each visit with the date and the type
of intervention performed.
- All the operations must be performed with the burner stopped
and the generator "cold";
- in order to avoid any start-up, even accidental, it is advisable
to remove the fuses of the electrical power line and signal
with a sign the prohibition to actuate the switch;
- if maintenance is performed by several people, agree before
starting work "who does what";
- close the fuel supply pipe;
- during cleaning wear all PPE provided for specific activities,
in strict accordance with the Safety Standards;
- carefully protect all equipment;
- for cleaning, use brushes and vacuum cleaners;
- when necessary to reassemble the components removed
for cleaning, carefully check the state of the gaskets and / or
provide for their replacement;
- protect screws and nuts with graphite grease which will facil-
itate their subsequent removal;
- after having set up the generator for a long period of inactiv-
ity, provide appropriate instructions to be placed on the gen-
erator for the operations to be performed before restarting it.
- At the restart, before turning on the burner, check the oper-
ation of the generator pumps and of the system.
